I got the cutter with the big wood ball on it, easier for me to hold on to. You just screw the case length gage into the end of the cutter and the shell plate onto the stud, and the end of that chucks into an electric drill. The edges of the shell holder are sharp and will eventually wear a blister on your fingers so be careful. Let me get a picture taken of mine and I will post it here in a few minutes.

It kind of sucks it's not the opposite, If I could install the case length into a drill press and keep it spinning while I hold the shellholder/brass in my hand.... I think that would make more sense

I went with the Lee Zip Trim and associated accessories. Less than $45 from Titan Reloading. The Zip Trim is a "pull the string" device and works well for me, easy one or two pulls on the string. I feel I have more control with that than with a drill motor system. Three jaw chuck accommodates most case sizes. I also use it for wiping lube from rifle cases and polishing cases.

I have started using the Lee Quick Trim Die and Deluxe Trimmer.
I did this because I needed to trim 204 Ruger cases and there is no other Lee alternative. I'm using it for 7.62x39mm as well. It's quick as the name implies.
